Difference being, these are not home play chips, they are in use at casinos even today.

Discovered on the tables on June 7, 2016, when I went to the casino for my Birthday Special Buffet Offer - a slice o' cake and a serenade by the Mariachis. I could have listened til the Moon went down. On second thought, I'd rather have eaten the Mariachis and listened to the Cake.
